To all whom t may concern,.-

Be it known that I, FRANC/rs A. WALsH, of Milwaukee, in the county ofMilwaukee, and

in the State of Visconsin, have invented certain new and usefulImprovements in Machines for Heading'Cans, &c.; and I do hereby deelarethat the following is a exact description thereof. Y

My invention relates to machines for for1ning, filling, and solderingcans, and will be fully described hereinafter.

In the drawings, Figure l is a front elevation of my machine. section ofthe same on a broken line, showing the turntable and its working parts.Fig. 3 is a vertical section of the machine on line :c x of said Fig. 2,and Figs. 4, 5, 6, and 7 are details of the same.

A is the stand, having a base, A', through which suitable fastenings maybe passed to fix the machine on top of a horizontal or slightlyinclinedtable or bench. A flange, Z), is formed at a proper heightl from saidbase A', around which the turn-table Bis adapted to rotate, beingsupported thereon by means .of its grooved flange b. On the inner topedge of said ange 1) is formed a ratchet, b2, and on the outer edge ofthe same is a bevel-pinion, b3. ings are fitted around said flangeProper bearhalf of its outer rim carries the ion c.

This last issecurely held in place during; the intermittences by a pawl, a, hung ona bearing-stud, c', in said stand A, and adapted to; engage its lowerend in the notches or teeth of, the ratchet b2 on top of iiange I) ofthe turn-i table until the upper end of said paw] a, comi?` ing incontact with the cama?, formed on inside face of said wheel D2, saidpawl c is dis3` The bevel-pin-V D, which runs in bearing-studs el d ofsaid stand A, andV carries the fastand-loose pulley (Z2. r[he straightpinion Ac of the annular wheel C meshes with pinions o2 and o, which runfreely on lower end of stems e and e', suitably mounted on arms E and Eof stand A. Said pinions c2 and cyrs alternately mesh with pinion e2,formed on bottom of each of the chucks F F, that are mounted in anydesirable number in said turntable B, provided for that purpose on itslower face with the bearing studs or sleeves b* b4. Each of said chucksF yis pivoted in said turn-table B on a stem, f, which is threadedin itscentral part, whereon works thenutf, by means of which thehead f2,carried on top of said stem f, may beheld lower or higher, according tothe varying A bead, f, of any desirable shape, is formed around saidchuck F, and a rod, f, inserted in the lower end of its stein f, isdesigned to keep said chuck F from turning as it comes in contact with afinger, a3, fixed at the proper point in the base A of said stand A.

Running loose on stein E ofarni E is the former e2, which is grooved andheld on aJ plane to correspond with each of said chucks F F. Projectingfrom said stand A, over the pathof said chucks F F, are the bearing-armsG G', in which are proper bearings for the vertical shaft H. This shaftII isprovidedwith a feather, h, to work in the groove of pinion II",that meshes with pinion di, keyed on front end of the driving-shaft D3.On the threaded lower end of said vertical shaft II is fastened the headH2, on the rim of which are properly mounted the formers or wheels h.The upper end of said vertical shaft H is provided with thebearing-collars h2 h2, `between which works the bifurcated end of theliftinglever J, hinging in its rear end on the fulcrumstud j About itscenter said lever J is notched on 4its upper and lower face, and on.said notches bear the beveled edges of a slot, 7c', formed in the centerof top bar, 7c, of the lifting-frame K, the bottom bar, k2, of saidlifting-frame K, which is suitably connected to the top bar, 7c, by theside rods, k3 7a, has in its center the slot k, and in said slot travelsthe crank-pin Z, carried on the front face of the IOO ' suitable device:

wheel L, keyed on front end of shaft D. Said crank-pin Z is adapted tobe moved more 'or less from the center of said wheel Lby means of thescrew m, to lengthen or shorten the motion of the liftingframe K,according to the varying height of the can. The can is held in place bythe following or any other I Projecting from t-he stand is the arm M, inthe outer end of which is journaled the stem n, carrying on its lowerend the inverted conical head n. Said stem a is threaded in its upperend for an adjusting-nut, n2, and has a spring, 0, coiled around itbetween the conical head n and the bearing-arm M, to press said head ndown onto the top of the can. On stud p of said stand A is mounted asuitable vessel, P', with apipe, p', close to its bottom, by means ofwhich the soldering -flux contained therein is dropped at proper pointson top of the can. Projecting also from said stand A is the arm O,supporting on its outer end the stem of the soldering iron by aset-screw, r. Said soldering-iron l? has the usual tip, r', and theheating-head s,which is made hollow and with vents or j ets t, to burngas conveyed to it through the hollow stem' s', connecting by pipe s2reservoir. y

Fig. 6 shows a part of the turn-table B and a countersunk chuck, F',which is inserted in place of the chuck F when the filling and coveringof the can are to be done.

The operation of the machine is as follows: Power being applied 'to thedriving-shaft D2, a continuous motion is imparted to the pinions c2 andd* through the annular wheel C and wheel D', while the turn-table Breceives an intermittent motion from the wheel D2. When the uncoggedportion of said wheel D2 passes with a suitable gasover the bevel-pinionb3 on flange of the turn` table B, the pawl a maintaining said turn-table in place, one of the chucks F F is standing under the head H2,revolved by shaft H, and brought down by the crank-wheel L, through thetraveling frame K, to bear against the can previously set on said chuckF, said head H2 completing its work around the can-body during theintermittence of the turn-table B. The

awl a is disengaged from the ratchet b2 as'the cogged portion of thewheel D2 engages with the pinion c of the turn-table, and the tablemoves around until the pawl a falls again in the ratchet b2, when thefirst chuck F, already operated upon and now brought in contact with theformer E2, is rotated by its pinion e2 engaging at the same moment withpinion c2, that is constantly kept in motion by the straight cogs ofpinion c on annular wheel C. In the meantime a second chuck F has beenbrought under the headingshaft H, and while the can inserted over saidsecond chuck is operated upon the former E2 takes against the lower endof the can revolved by the firstl chuck F, and the soldering-flux isdropped on the upper end of said can. A third move of the turn-table Bwill then bring the said first chuck comes again under the head H2 I),held in the proper positiony lanism already shown, or by operated eitherF under the projecting arm O, where the solder is applied, the secondchuck bringing its can, in the meantime, to the former E2 andthefluxpipe, while a third chuck F presents its canbody to the action ofthe head H2. After the solder has been applied in turn to each of thecans on said chucks F and their followers, if it is desired to do thefilling and covering on the same machine, each or any of said chucks isremoved from the turn-table, and theA countersunk chuck F is put in itsplace. The can is then placed on said chuck F, and, during theintermittences of the turn-table, the can is filled, the cover isinserted, and,

of vertical shaft H, said cover is secured in its place, and the can isready for shipping. y

It will be understood that the soldering may be done while the can isbeing beaded, thus dispensing with the intermediate pinion, c.

One of the features of my machine is the device by which the differentparts of the work of canning may be independently carried on in onemachine.

I do not mean to confine myself to the`device as shown in the drawings,as it may be modified variously without departing from the spirit of myinvention. For instance, the power may be applied from below; or I mayraise and lower the shaft H by either hand or foot power, or connect itwith the drivingwheel by pinions and a cam instead of by rods and alever; or the chuck may be vertically reciprocated from below.

I have shown a construction in which the can is held stationary while itis being headed; but, instead, I may gear the can'chuck to the drivingmechanism and disconnect the shaft H from it, s o that the can willrevolve under a stationary head; or both heads may be disconnected fromthe revolving mechanism, (when heads of certain shape are used,) and thehead H2 may be driven down by the mechany other suitble for the purpose,(see Fig. 7 or I mayimpart a rotary motion to both the can chuck andhead, but in opposite directions, in which case I may bead the can whileit is being headed. I may also entirely dispense with the turn-table Band its driving-connections, and, in any suitable support, I may mountthe head H2, with its revolving or fixed formers h', and revolve andreciprocate said head against a stationary can-chuck, F, suitablysupported under said head; or I may mount said head H2 to revolve, withits revolving or fixed formers h', against a non-revolving butreciprocatin g chuck, F; or, again, said head H2 may be fixed on itssupport and be operated against by a revolving and reciprocating chuck,F; or, lastly, said head H2, carrying its revolving or fixed formers h',may be reciprocated Without revolving against a revolving can-chuck, F,both the head H2 and the chuck F being by hand, foot, or any othersuitable means.

Having thus described my invention, what I roo claim as new, and desireto secure by Letters Patent, is-
